Specification of Letters Patent.

Patented May 23, 159168..

. Application filed January 13, 1916. Serial No. 71,876.

Be it known that I, LOUIS BLUMnn'rHAL, a citizen of the United States,residing at Brooklyn, county of Kings, and State of New York, haveinvented new and useful Improvements in Snap-Fasteners, of which thefollowing is a specification.

This invention relates to a device for securing the opening of a garmentwhich can readily be attached and cannot accidentally become disengagedwhen in action.

The invention comprehends a plurality of spring loop members projectingoutwardly from a base member, and a yoke bar adapted to coact with themembers.

The essential object of the invention is to provide a space betweentheloop members so that when it is desired to have the yoke bar connectwith the loops it can be inserted in the space to spread the loops.'When the bar ispressed the entire distance into the opening the loopswill contract by reason of their inherent resiliency and thus positivelylock the yoke bar in place.

The. deviceis designed to provide meansfor preventing the yoke bar fromlaterally shifting after it is pushed into place between the loops.

The invention is more fully descrlbed 1n the following specification andclaims and illustrated in the accompanying drawing in which:

Figure 1 represents a front viewshowmg the device attached to a garment.Fig. 2 is a side view of a yoke bar. Fig. 3 is a front view of a springloop member showing the yoke bar snapped in place. Fig. 4 is a plan viewof the same.

In this drawing is shown a snap keeper preferably constructed of asingle length of spring wire having a pair of eyes a formed at adjacentends of the wire. These eyes serve to 'firmly attach the device by meansof stitches b to theflap of a garment c as indicated in Fig. 1. A. pairof logp members (Z are formed by convoluting the wire on each side of anopening 0 at the central portion of the device. The loops are oinedtogether by a contiguous base member 7 which is preferably concaved.

As indicated in Fig. 4 each loop has a plurality of convolutions to forma double outwardly projecting loop one being diametrically opposite andaxially ad acent the other. There are thus two pairs of loops one pair(i being joined together by the base 'member f-While the other pair dare united to the eyes a by branch wires 9 extending from the lowerportions of the loops.

'The yoke connection includes a bar provided with a concavecl centralmember 1:.

and having convexe'd side portions 11 w are united to a pair ofoppositely located Y eyes 7' by the upward extensions is. The yoke isformed of a single piece of wire and the eyes are for the purpose ofattaching the yoke by sewing to the garment as shown at vm in Fig. 1. Itwill be seen that whenthe yoke member is placed in alinement or registerwith the space between the outwardly projecting loops and pressed homethe central concaved portion will rest on the base member f with theprotruding convexed portions i forming stops on each side of the base toprevent lateral playof the yoke. In this connection it should be saidthat when the yoke bar is pressed into the opening until it reaches theaxis of the loops it will compress them, hence widening the opening.Then when the yoke bar is pushed farther into the opening the jaws ofthe loop will spring together and the bar will snap onto the basemember. In this position the yoke bar cannot be disconnected frombetween the jaws of the loops until they are again snapped apart by thewithdrawal of the oke bar. a

While I have shown and claimed this device as being made of wire, itwill of course be understood that I do not limit myself to this materialand that the device may be made of any suitable material.

I claim:

1. A snap fastener comprising a base member, a plurality of spacedspring loops projecting outwardly from the base, and means for fasteningthe device to an article; combined with a yoke member adapted forinsertion between the loop members.

2. In a snap fastener the combination with a pair of outwardlyprojecting spring 'loops formed of wire, eyes extendingfrom thelower'portion of the loops and including a base member to join theloops, of a adjacent ends of the wire, of a yoke member adapted forinsertion between the loops to coact with the base, and means forpreventing lateral movement of the yoke member.

4. In a snap fastener the combination with a pair of outwardlyprojecting spaced spring loops formed of wire, a base member joining theloops, including eyes located at adjacent ends of the wire, of a yokemember adapted for insertion between the loops and having protuberancesfor preventing lateral movement and to coact with the base member.

5. In a snap fastener the combination with a pair of outwardlyprojecting spaced Copies 01 thjl spring loops-formed of wire, a basemember joining theloops, and eyes located at adjacent ends of the wire,of a yoke member adapted for insertion between the loops havmg upwardextensions with eyes includingv 20 concaved and protuberant portions forpreventing lateral movement and to coact with the base member.

In testimony whereof I have hereunto set my hand in the presence of twosubscribing 25 commissioner oi Patents,

Washington, D. 0.
